1) What is Info Sec? Flashcards
Protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction.
information security
Confidentiality, integrity, or availability?
A PIN code is required to log into an information asset.
Confidentiality
Confidentiality, integrity, or availability?
Permissions are implemented to ensure access is restricted.
Integrity
Confidentiality, integrity, or availability?
All systems are operational and accessible.
Availability
Confidentiality, integrity, or availability?
Information is being protected by role-based access.
Confidentiality
Confidentiality, integrity, or availability?
Data have not been modified from the original creation.
Integrity
Ability to prevent data from being changed in an unauthorized manner.
Integrity
Ability to protect data from those who are not authorized to view it.
Confidentiality
Ability to access data when it is needed.
Availability
Proper attribution to the owner or creator of the data.
Authenticity
Physical disposition of the media on which data is stored.
Posession
How useful the data is.
Utility
Attack Type:
Eavesdropping on a phone.
Interception
Attack Type:
DoS on a mail server.
Interruption
Attack Type:
Altering a web server config file.
Modification
Attack Type:
Spoofing emails.
Fabrication
Something that has potential to cause harm.
Threat
Weaknesses that can be used to harm us.
Vulnerability
Likeliness that something bad will happen.
Risk
The value of the asset is used to assess if a risk is present.
Impact
Identifying and categorizing the assets we are trying to protect.
Identify Assets
Begin to identify and categorize threats that could harm our assets.
Identify Threats
Identify the weakness that exist in our assets.
Assess Vulnerabilities
Assess if both a threat and a vulnerability exist.
Assess Risks
Put controls in place.
Mitigate Risks
What type of control should be used to mitigate the risk:
Server room access.
Physical
What type of control should be used to mitigate the risk:
Work hour restrictions not set.
Logical
What type of control should be used to mitigate the risk:
No acceptable use form for users.
Administrative
What type of control should be used to mitigate the risk:
Unguarded building.
Physical
What type of control should be used to mitigate the risk:
Password lockout not set.
Logical
(T/F) Using the concept of defense in depth we can protect ourselves against someone using a USB flash drive to remove confidential data from an office space within our building.
True
Protects information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction.
Information Security
Companies that process credit card payments must comply with this set of standards.
PCI DSS
Companies that process credit card payments must comply with PCI DSS. What does PCI DSS stand for?
Payment Card Industry Data Security Standard
Used to keep something private or minimally known.
Confidentiality
Refers to the ability to prevent our data from being changed in an unauthorized or undesirable manner.
Integrity
Refers to the ability to access our data when we need it.
Availability
A type of attack, primarily against confidentiality.
Interception
Something that has the potential to cause harm to our assets.
Threat
A weakness that can be used to harm us.
Vulnerability
The likelihood that something bad will happen.
Risk
An attack that causes our assets to become unusable or unavailable for our use, on a temporary or permanent basis.
Interruption attack
An attack that involves tampering with our assets.
Modification attack
A model that adds three more principles to the CIA triad: possession or control, utility, and authenticity.
Parkerian hexad
The physical disposition of the media on which the data is stored.
Possession or control
Allows for attribution as to the owner or creator of the data in question.
Authenticity
Refers to how useful the data is to us.
Utility
An attack that involves generating data, processes, communications, or other similar activities with a system.
Fabrication attack
One of the first and most important steps of the risk management process.
Identify assets
A multilayered defense that will allow us to achieve a successful defense should one or more of our defensive measures fail.
Defense in depth
Based on rules, laws, policies, procedures, guidelines, and other items that are “paper” in nature.
Administrative controls
Sometimes called technical controls, these protect the systems, networks, and environments that process, transmit, and store our data.
Logical controls
Controls that protect the physical environment in which our systems sit, or where our data is stored.
Physical controls
Involves putting measures in place to help ensure that a given type of threat is accounted for.
Mitigating Risk
The risk management phase that consists of all of the activities that we can perform in advance of the incident itself, in order to better enable us to handle it.
Preparation phase
The risk management phase where we detect the occurrence of an issue and decide whether it is actually an incident so that we can respond to it appropriately.
Detection and analysis phase
The risk management phase where we determine specifically what happened, why it happened, and what we can do to keep it from happening again.
Post-incident activity phase
To completely remove the effects of the issue from our environment.
Eradication
Taking steps to ensure that the situation does not cause any more damage that it already has, or at the very least, lessen any ongoing harm.
Containment
Restore to a better state.
Recover
The Interception attack type most commonly affects which principle(s) of the CIA triad?
Confidentiality
The Fabrication attack type most commonly affects which principle(s) of the CIA triad?
Integrity and Availability
What is the first and arguably one of the most important steps of the risk management process?
Identify assets
Something that has the potential to cause harm to our assets.
Threat
During what phase of the incident response process do we determine what happened, why it happened, and what we can do to keep it from happening again?
Post-incident Activity
Controls that protect the systems, networks, and environments that process, transmit, and store our data.
Logical controls
